The property borders on national forest and there are plenty of nearby mountain activities right out the doorstep. Walk to the White River from the house, hike in the national forest, visit Crystal Mountain Resort, or go into Mt. Rainier National Park. After your mountain adventures, come back and take a dip in the hot tub. The large dining room can fit the whole group. BBQ on the porch or cook in the big kitchen.
There is a MIL apartment in the basement of the house that is often occupied by the owners. The MIL will not be occupied July-Aug 2017. It has a separate entrance and there is no shared space. The main 3 bedroom, 2 bath house, hot tub, fire pit, etc. are for your use exclusively. You can make special arrangements to rent out the house with a guarantee that the MIL will not be occupied or make arrangements to rent the MIL as well for the extra bedroom, bath, kitchen and living space.
